Re: Hemi spark plugs
If you buy Iridiums, you still have to change them per the manual -- as long as you are under warranty. Thus, you'll be wasting money. I'd stick with coppers also. Chrysler is silly like that, and there must be a reason. Neons ran best on coppers as well (had a 2nd gen back in the day).
